By so'having the base `0f rthe triangular 'shapedap'eXportion 26 of less length than 'the width of the attaching flanges '25, allows'forthe inner edge 27l0f 1the attachinglflanges toprojectslightly past @the atl taching'edge`28'of the `triangular?'shaped endA f Vwalls 22. The object! in 'solh'av'i'ng the edge" These attaching flanges aside from pro-v viding a suitable attaching edge for the sections 'D and E, also serve as strengthening.

means for the sheet inetal shield portions.v

The opposite orfree edge of each of the, shield or deflecting portions 2O is provided with an outwardly curled edge j and which curled or turned. edges 30 act for holding the outer edges of the duplicate sections in tele-k scopic relation. These curled edges 30- are formed by curling that portion of the blank indicated bythe numeral v31 in Figure 6. Provided in each Vof the shield portions 20, immediately inwardly of the curled edge 30, is an elongated slot 32, and which slots when the duplicate sections are Vin assembled rela-` tion7 4will align one with the other.v These slots 327 and which have their inajor dimensions extending longitudinally of the shields 20, are preferably formed adjacent the inner ends of the shield portions and in direct- Vtransversf-i alignment with the slots 29.

Extending through the aligning slots 32, is a headed clamping bolt 32 having a threaded inner end for receiving a suitable wing nut 33 which serves for drawing the free edges of the shield portionsV at their inner ends into surface contact with one another. The

head of the bolt 32 is adapted to engage an elongated washer 34 of a length slightly more than the combined lengths'of the slots 32 so that when the duplicate sections are in their fullest extended position, the elongated wash-y er 34 will wholly cover the slots 32 and thus j prevent possible entrance of water through the slots when the'ventilator is used in a position at the top of the window casing. By so having the slots 32 spacedinnnediately behind the curled edges 30, the curled edgeof the section will prevent rotation of the elon-r.

gated washer 34 and thus retain the washer in closing relation over the slots.

Referring particularly to the forming of the duplicate sections as illustrated in Figure 6, it will be seen that the portions 40 forni the shield portions 20. the portionsv 4.1 forni` the attaching flanges 25. the portions 31 form the curled edges 30, and that the portions. l2 provided by the diagonal line 43 form the triangular shaped end Walls 22. The di-` agonal line 43, when the sheet of metal is divided for forming the duplicate sections D and E. forms theV attaching edge 28 and which as will be apparent iswof greater length than either the length of the fold line 21 or the Vlength ofthe base edge 4.5. v

the elongated washer 3st and thus it will be seen that the only waste .material will be that which is struck from the blank for forming the slots 29 and 32. The washer 34 is provided 'with a centrally disposed square aperture t7 through whichthe bolt 32 may extend. Y j

The triangular shaped end walls 22 are each provided along their attaching edges 28 Vwith apertures i8 through which suitable-fastening eleinentsl-Q may extend for attachnient of the end walls to the side frame of the window casing. The attaching flanges 25 may also be provided between the slots and end walls with suitable apertures through which suitable fastening elements may also extend for further attachment of the ventilator to the window casing.

l/Vhen applying one of the improved ventilators to the lower side of the windowv casing as designated at C, for the admitting of air upon raising of the lower sash 11, the ventilator is :first disposed with the flanges 25 resting upon the stool 17 and the duplicate sections D and 'E adjusted so that the triangular shaped end walls 22 engage the confronting faces of the inner. stopV beads 12. The free edges 27 of the attaching flanges are disposed flush with the outer edge ofthe stool 17 and in which position it will be observed that the offset attaching edges 28 of the end walls are spacedV out of possible contact with the side rails of the sash 11. rfhis offsetting of the attaching edges 28 prevents possible marring of the side rails of the window sash when being raised or lowered. VWhen inv this.

position7 the fastening elements 4:9 may be driven or screwed into the stop beads 12 thru Vthe apertures 4.8 for disposing the shield portions 2O 'in an upwardly and inwardly inclined position so that upon slight raising of the lower sash air may be admitted Vat the lower portion of thevwindowcasing and be deflected upwardly into the room by the angularly disposed shield portions 20. A round headed screw threaded fastening element may then be passed thru the aligning slots 29 and turned into the stool 17 for rigidly securing the medial portion ofthe ventilator in surface contact .with the upper face of the stool 17 and with the free edge 27 extending flush with the outer edge of the stool as illustrated in Figure 1. Y

With the free edge 27 of the flanges so'extending flush with the outer Vedge of the stool 17, it will be seen 'that any rain or snow entering thru the opening will strike the inclined shield 20 and be directed over the edge 27 Sli bach to the upper inclined surface of the sill"l If desirable, additional fastening elements may be passed thru theflange apertures 50 for anchoring the end portions of the flanges to the stool 17. After the ventilator has been so secured to the stop beads 12 and the stool 17, the wing nut 33 may be tightened for retaining. the duplicate sections D andE in y adjusted telescopic relation. In this position in telescopic relation.

it will be seen that the curled edges provide a protecting edgel along the free edge of the shield portions 20, and that the curled edges 30 also serve as reinforcement portions and also aid in holding the duplicate sections It will also be seen that a portion of the triangular shaped end walls 22 projects upwardly past the upper edge of the shield portions 20, and thus'prevents likelihood of snow or rainbeing driven past either end of the ventilator should the lower rail of the sash 11 be raised to a position substantially horizontal with the upper edge of the deflector 4portions 20. f

When one of the ventilators is used in a position as shown at B, the same serves as a hood or storm shield .for permitting of the upper sash 10 to beflowered a limited distance without likelihood of beating rains or Winddriven snow to enter-'the room when the sash 10 is lowered for Ventilating purposes.`

As will be seen by observing Figure 1, and referring particularly to the ventilator B, it will be seen that the attaching flanges 25 are secured to the header bead 15 with their free edges flush with the inner edge of' the header bead, and that the triangular shaped end Walls of the ventilator are secured to the confronting faces of the outer stop beads 13 with the attaching edge 28 spaced slightly from the inner edges of the stop beads. Upon inverting of the ventilator for attachment as shown at B, it will be seen that the curled edges 30 act as a gutter extending throughout the length of the ventilator and servingv'to conduct-rain olf at both ends of the ventilatorl and thus prevent the rain from being driven into the room when the sash 10 is lowered; When used in this. position, the elongated washer 34 serves for fully covering the slots v32 und thus prevents entrance of water through the slots. Vith the triangular shaped end walls 22 so-formed with the base edge 45 extending at a right angle to the bending line 21, provides a construction whereby a portion of the end walls will extend below the gutter formed by the curled edges 30 and thus prevent likelihood of the water being directed off the ends of the gutter to enter thru the opening formed by the lowering of the sash 10.

From the foregoing description it will be apparent that an improved type of reversible window ventilator has been provided being of such construction as to permit of the same being used at either the top or lower portion of a. double hung Window construction, and

which ventilator is of such vconstruction as to .permit of the sections thereof to be economi* .end wall bent at a rightl angle at one end of the shield portion with the attaching edge of each end wall spaced intermediate the edges ofthe flanges and slightly'inwardly from the free edge of said iianges.

A ventilator comprising a pair oil dupli- Vcate telescopic sheet metal sections each embodying a shield portion having a flat attaching flange formed along one edgevthereof and f provided adjacent itsinner end with an elongated slot, and having a curled edge formed along the opposite edge of the shield portion and extending in the opposite direction from said flange, each of said shield portions also being provided near their inner ends with elongated slots arranged `adjacent their curled edge, and an integral triangular shaped end wallbent at a right angle at one end of the shield portion, and a clamping bolt extending through the aligning slots of the shield portions for clamping the free ends of the shield portions in surface contact with one another, said slots of the attaching flanges to receive fastening elements therethru for mounting of.` the central portion of the ventilator. v v 3. Ina ventilator comprising a pair of companion vtelescopic sections each embodying a shield portion provided with interfitting curled edges and elongated slots provided in the shield portion adjacentthe curled edges, means'for adjustably clamping the,

sections in longitudinally adjusted positions,

comprising an elongated washer of' a length at least equal to the combined length of said slots, said washer being held in position over the slots by the arcuate surface of one of the curled edges', a headed vclamping bolt extending through the washer and the. aligning slots, and a wing nut threadedupon the inner cnd of 'the bolt.
